Problems solved by technology

[0002] In the conventional cleaning process, it is only soaked in the mixed solution of hydrochloric acid, hydrofluoric acid and deionization, and cleaned for 5 minutes. This method can only remove part of the organic components, and the effect of removing particles and metal ions on the glass surface is poor.

Abstract

The invention discloses a cleaning method for removing impurities on a glass surface. The cleaning method comprises the following steps of (1) placing glass to be cleaned in a first cleaning solution for ultrasonic cleaning, wherein the first cleaning solution comprises hydrogen peroxide, ammonia water and water; (2) putting the glass cleaned in the step (1) into a second cleaning solution for ultrasonic cleaning, wherein the second cleaning solution comprises hydrofluoric acid, hydrochloric acid and the water; and (3) cleaning the glass cleaned in the step (2) in deionized water, drying, and finishing cleaning. By means of the cleaning method, metal particles on the surface of the glass can be removed, grease, grinding fluid, metal ions and other impurities on the surface of the glass can be removed, and the impurities on the surface of the glass can be cleaned at a time.

Description

technical field [0001] The invention relates to a cleaning method for components, in particular to a cleaning method for removing impurities on a glass surface. Background technique [0002] In the conventional cleaning process, it is only soaked in the mixed solution of hydrochloric acid, hydrofluoric acid and deionization, and cleaned for 5 minutes. This method can only remove part of the organic components, and the removal effect on the particles and metal ions on the glass surface is poor. Since the previous process is polishing and grinding, a large amount of grease, grinding fluid and metal ions have accumulated on the surface. Therefore, a more effective method is needed for cleaning. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a cleaning method for removing impurities on the glass surface. [0004] In order to achieve the above object, the technical solution adopted by the pr...
